The fee is charged to all properties within Highland Village that have impervious surface area (hard surfaced areas that either prevent or retard the natural entry of water into the soil - i.e. house footprint, driveways, sidewalks, etc.).
A rate charge of $1.40 is applied per 1,000 square feet of each residential or commercial lot's total impervious cover. The average home in Highland Village has 4,094 square feet of impervious cover, which equates to monthly fee of $5.73.
